Mr. Don Seaquist

Plano, Texas 75093

Dear Don:

  It is our pleasure to confirm our offer of employment with EMBREX as Vice-
President, Finance & Administration, effective on September 9, 1996, contingent
upon your submitting to and obtaining a negative result from a chemical
screening for drugs and alcohol. Please call Human Resources to schedule your
sample collection. Your starting compensation will be at the rate of $11,250.00
per month.

  Upon commencing employment at EMBREX, you will be entitled to receive an
Incentive Stock Option for 31,500 shares of EMBREX Common Stock at an option
price per share at fair market value on date of grant. These options will vest
equally over four years from the date of grant. This stock option is subject to
the approval and grant by the Compensation Committee of the EMBREX Board of
Directors at their next scheduled meeting.

  Regular, full-time employees of EMBREX are entitled to participate in all
company-sponsored benefit plans. Each plan has terms and conditions regarding
enrollment, which you must discuss with our Human Resources office on your first
day of employment. A booklet describing our current employee benefits and plan
highlights are enclosed for your information. Please review the medical, dental,
LTD and supplemental life plans and make your decision about which plans you
would desire to participate in. Also enclosed is an information package about
our 401(k) retirement savings plan. You are eligible to enroll on your first day
of employment and will need to make several decisions about your employee and
employer investment options, even if you elect not to participate. Please review
the information, complete the enrollment form and beneficiary designation (even
if you elect not to contribute) and bring to your orientation.

  As a relocating employee, and upon presentation of receipts, you will be
entitled to reimbursement for actual and reasonable relocation expenses
including:

  (bullet) Two house (or apartment) hunting trips for you (and your family) not
to exceed 7 days.

  (bullet) Relocation of household effects; and

  (bullet) Temporary living expenses up to 30 days.

  As a homeowner, you are entitled to payments associated with the sale/
purchase as follows:

  (bullet) Real estate and other fees (except discount points, association
fees, prepaid items (escrow), memberships): and

  (bullet) Good faith estimates on closing costs (obtain 2 quotes).

  You are also entitled to a direct incidental cash allowance of $2,000.00,
which is fully taxable. You may submit a check request at any time during the
relocation process, to receive this payment. To offset the anticipated loss on
the sale of your home, we will give you a one-time settlement in the amount of
$15,000.

  Since the Company's relocation policy is a personal arrangement between you
and the Company, you should not discuss it with or make copies of this agreement
available to anyone outside your immediate family.
